alot depends on the color and the color of sealer the painter is going to use. With most basecoats being a 1 to 1 mixing ratio 2 quarts of base should be more than enough
Just remember the better quality the paint the better it usually covers. I use the usually lightly. Of coarse that has a lot to do with the color to. lol
With the right sealer 1 quart should be enough. Are the Parts new? Cause if they are i see no point in blocking and primering agian. or even if they are painted you dont need to block and primer unless it had body work. If its painted already just sand it down with 600 with the d a, seal it, paint it, and clear it.
hood is a VFN still the way it came needs repairing in the corners becuase they have never heard of protecting them. Wing is already primed and blocked need to prime it again then we should be ready after one last go with the paper.
I think a quart will be more than enough, if your using HVLP gun. It usually takes me 3 quarts of paint (color) and a gllaon of clear to paint an entire car (1st gen camaro) . Use a primer/ or tinted sealer that is close to the color of the car and 3 coats of color should be fine. I just did a hood off a 98 camaro and used about a half qt.
how much paint.
